In my never ending quest for a decent To Do app, I blundered into this article. I’m currently using ToDoist and Habitica, but hadn’t heard of Google Keep. I’m going to try Google Keep as well because it’s free. Free is good. Free with pretty colors and an app that looks like a notepad is even better. I’ll post which one I like the best out of the three and let you know which one worked for me.
